PURPOSE: To protect wafers against pressure due to vibrations, fall or the like to prevent the wafers from being broken, to prevent the wafer surfaces from being contaminated with dust or the like and to enable to safely transport the expensive wafers by providing a wafer case for transport with a box type main body which carriers the wafers and a press plate and a cap which protect the wafers.

CONSTITUTION: The left and right sidewalls 4 and 5 of a main body 1 are erected the upper half parts thereof, are curved the lower half parts thereof inward and are further drooped to couple with a bottom plate 6. A press plate 2 is formed into a rectangle, the both sides which parallel the main body sidewalls are formed into comb-shaped elastic pieces 16, each elastic piece 16 has two strips of parallel supporting pieces 17 in the center of the internal surface and the press plate 2 is fitted into the main body upper part to elastically suppress and support the wafers at the four points from the upper part thereof, to prevent the wafers from being vibrated, and at the same time, to disperse an external force to prevent the wafers from being broken. A cap 3 is fitted into the main body 1, but the cap has edges 9 which reinforce the cap, the rear edge is provided with engagement protruded pieces 20 which engage the cap with the main body and the protruded pieces 20 are engaged with the recessed parts 11 for engaging the cap of the main body 1 to execute the opening and shutting and the attachment and detachment of the cap.
